The sequential driving of the first driving cylinder 182 , the clamp 181 , and the second driving cylinder 183 and the driving for vacuum adsorption and vacuum adsorption release of the packaging material chuck 160 are performed by a control unit not shown. Controlled. The control unit also controls the rotational driving of the outer cylinder 130 as described above.

Next, as shown in FIG. 8 , the upper adsorption part 191 of the inlet expansion unit 190 rises in a state in which the upper ply of the packaging material 20 is adsorbed, and the lower adsorption part of the inlet expansion unit 190 ( 193) descends in a state in which the lower ply of the packaging material 20 is adsorbed, and the front inlet of the packaging material 20 is sufficiently widened. The control of the inlet expansion unit 190 is controlled by the aforementioned control unit.

Next, as shown in FIG. 9 , the vacuum adsorption state of the mask chuck 150 with respect to the mask 10 is released, and, for example, a push actuator 170 that may have a pneumatic cylinder structure is installed on the mask chuck 150 . By pushing the placed mask 10 forward, the mask 10 passes through the guide hole 141 and then is inserted into the packaging material 20 . The driving of the push actuator 170 and the driving for vacuum adsorption and vacuum adsorption of the mask chuck 150 are controlled by the above-described control unit.

After that, the packaging material into which the mask is inserted is rotated together by the rotation of the outer cylinder and unloaded by a separate unloading device. .

By continuously repeating the above process, the mask can be automatically and quickly packaged in the packaging material.

While the present invention has been shown and described in connection with preferred embodiments for illustrating the principles of the invention, the invention is not limited to the construction and operation as so shown and described, and is not intended to be limited by the appended claims. It will be understood by those skilled in the art that many changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention.
